ABSTRACT:
A security grating (1) for securing store windows (2) is constituted of a mesh (3) of overlaying horizontal bars (4) and vertical bars (5). The security grating further comprises a vertical frame member (6) on each lateral edge. The frame member (6) has a recess (10) with a depth corresponding to at least half the mesh width (9) between vertical bars. Thus, the mesh can always be cut so that the outermost vertical bar is located in the recess (10). As the vertical bar (5) can be positioned at an arbitrary depth in the recess (10) there are no specific requirements for exact tolerances when mounting the security grating (1) around a window (2).
